American Airlines announced on Wednesday that it completed another big step towards being one airline after its merger with US Airways.
On Wednesday, the Federal Aviation Administration (FAA) approved American Airlines’ single operating certificate. Since the merger in 2013, the two carriers have flown under separate operating certificates from the FAA. However, as of Wednesday, the FAA will recognizes that they can legally operate as one airline under a single operating certificate, which will operate under the name of American Airlines.
In other words, as of Wednesday both US and American will begin using the “American” call sign when American/US Airways pilots communicate with air traffic controllers. US Airways will no longer use the call sign “Cactus” when speaking to ATC. US Airways inherited the “Cactus” call sign from America West Airlines in its 2005 merger.
The new American recently combined frequent flyer programs and is expected to have one reservation system by the end of the year.
